TRUNK-FASTENER.

SPECIFICATION forming part of Letters Patent N 0. 666,397, dated January22, 1901.

Application filed November 7, 1900. Serial No. 35,755. (No model.)

To (.tZZ whom it may concern:

Be it known that We, ALBERT L. SESSIONS, residing at Bristol, in thecounty of Hartford, and CHARLES PURRINGTON, residing at Pequabuck, inthe county of Litchfield, State of Connecticut, citizens of the UnitedStates, have invented certain new and useful Improvements inTrunk-Fasteners, of Which the following is a specification.

Our invention relates to improvements in trunk-fasteners; and the mainobjects of our improvement are simplicity and economy in constructionand efficiency in use.

In the accompanying drawings, Figure 1 is a front elevation of ourtrunk-fastener. Fig. 2 is a horizontal section of the same on the lineat at of Fig. 1. Fig. 3 is a vertical section of the lower member of ourfastener on the line@ 3 of Fig. 1. Fig. 1 is a detached front elevationof the base-plate of our fastener. Fig. 5 is a detached elevation of thespring-box. Fig. 6 is a detached front elevation of the base-plate ofour fastener in a modified form, and Fig. 7 is a side elevation of thespring-box therefor.

Our fastener consists of a keeper portion A for being secured to the lidof a trunk and a spring-loop or latch portion B for being secured to thebody of the trunk. The latch or loop portion consists of a base-plate c,spring-box d, loop h, and spring n, the said parts in their generalconstruction and combination being old and hereby disclaimed, exceptingas they embody the improvements hereinafter more specifically described.

Our improvements relate more particularly to the construction wherebythe springbox is secured to the base-plate, some of the advantages ofwhich will be hereinafter referred to. The base-platec is provided atits upper part with lugs 8, recessed on their back sides to receive thelaterally-projecting lugs 9 on the spring-box d and with openings 10along the inside edges of the said recessed lugs 8 to admit that portionof the spring-box from which the lateral lugs project. As shown in Fig.4:, these openings 10 extend to the extreme upper edge of the baseplate,so that they are open at the top. In addition to the lateral lugs 9 oneach side of the spring-box at its upper part We form on each side belowthe lugs 9 the dowel-pins 11 for being received in the dowel-sockets 12of the base-plate and with a rivet or stud 13 preferably integral forentering the hole 14 in the base-plate. The lower portion of thespring-box is of an ordinary form and made to receive and hold thespring 72, against which the ordinary cam 15 of the snap or spring-looph bears in the ordinary manner. The spring-box is also provided with theordinary recesses in its side walls to form bearings for the cross-barat the lower or inner end of the loop h. The upper end of the spring-boxhas a central dowel-socket 16 to receive the dowel 17 on the lower endof the keeper A, the contour of the said dowel being indicated by brokenlines in Fig. 1. One advantage of our improved construction ofinterlocking the base-plate and spring-box together is that theinterlocking devices are arranged at the upper part of the plate and onboth sides of the middle, so that a central socket for the dowel of thekeeper may be employed in connection therewith.

The base-plate and spring-box are assembled after putting the spring andloop in position in the spring-box by placing the springbOX on the frontface of the base-plate with the lugs 9 just above the upper edge of thebase-plate, so as to register with the recesses in the back of the lugs8, then drawing the spring-box downwardly to engage the said lugs untilthe dowel-pins 11 register with the dowel-sockets 12 and the rivet 13registers with the rivet-hole 14, and then forcing the spring-b0x towardthe base-plate to engage the said dowel-pins and rivet therewith, afterwhich the whole is secured by riveting the end of the rivet 13.

In Figs. 6 and 7 We have shown a modified form of base-plate andspring-box, in which c is the base-plate and d is the spring-box. Thisdiffers from the first construction, in the fact that the recessed lugs8 are a little below the top edge of the base-plate and that theopenings by the side of the said lugs are notopen at the top. The lugs 9on the spring box are also correspondingly lowered. The parts areassembled in the same way, only the spring-box is first placed in frontof the baseplate with the lugs 9 below the lugs 8 instead of above them,and consequently the box is moved upwardly instead of downwardly toengage the said lugs and to bring the springbox into the position forhaving the dowelpins 11 and sockets 12 and rivet 13 and its hole 14register with each other. The interlocking lugs of the base-plate andspring-box are so nearly alike in the two constructions that ahorizontal section of the first construction on the line was of Fig. 1is precisely the same as a similar section on the line 10 w of Fig. (3,supposing the spring-box were in place on the base-plate, and thereforeFig. 2 may be considered as illustrative of both constructions.

Another advantage of our improvement is that there is only one rivet orlug to be bent in order to hold the parts in place, and thus a strongerand more durable article is produced than in a construction whereseveral lugs have to be clenched or riveted. The

dowel pins and sockets 11 12 help to hold the "spring-box againstlateral strain.

e claim as our invention 1. In a trui1kfaste11ei', the combination ofthe base-plate having the recessed lugs on each side of its verticalmiddle at its upper part with openings along the side edges of the saidlugs and the middle rivet-hole at its lower parl, with the spring-boxhaving at its upper part the two laterally-projecting lugs for engagingthe said recessed lugs of the baseplate and the rivet at its lower partfor being secured in the said rivet-hole in the base-plate,substantially as described.

2. In a trunk-fastener, the combination of the base-plate having therecessed lugs on each side of its middle at its upper part with openingsalong the side edges of the said lugs, the dowel-sockets on each sidebelow the said recessed lugs and the middle rivet-hole at its lowerpart, with the spring-box having at its upper part the twolaterally-projecting lugs for interlocking with the said recessed lugsof the base-plate, dowel-pins on its sides be low the said lugs forengaging the said dowelsockets of the base-plate and the rivet at itslower part for being secured in the said rivethole, substantially asdescribed.
